Neuroscience: My life with Parkinson's : Nature News & Comment

Neuroscience: My life with Parkinson's : Nature News & Comment: I was diagnosed with Parkinson's more than two years ago. From that day, I have had a different relationship with the brain — my scientific focus for the past 20 years. I now know what it is like to have a brain disorder and can explore its manifestations first hand. Take the very peculiar symptom known as 'freezing'. Occasionally, when I attempt to lift my hand it well ... won't. Notice that I didn't say can't. There is nothing wrong with my arm. It is still strong and capable of moving, but I have to put effort, even focus, into getting it to move — frequently to such a degree that I have to pause whatever else my brain is doing (including talking or thinking). Sometimes, when no one else is around, I use my other hand to move it.
